Overall the design and theme is really unique and well done. One thing I would say is that there is an inconsistency with the size of your lowercase letters. For example the ‘g’ and ‘y’ should come below the letter. It is also important to make the taller letters larger. I think the pattern you have with some of your Capital letters, for example B and E could be stretched to other letters, such as F, R. I think you should also try and keep a constant ‘theme’ throughout your alphabet, to show that the lowercase letters are linked with the uppercase ones. For example your lower ‘o’ could look more like the Capital one. The use of patterns is really clever and well thought out, it is a great example of experimentation and free play. A great job

An added note would be to try and add the hole pattern in the capital B to other letters such as the Capital P or R, to see if it affects the overall appearance of the alphabet. It would be an ideal way to help keep the alphabet consistent
